Briefly describe the three primary types of mobile wallet apps and identify the examples of each type

Sure, here are the three primary types of mobile wallet apps:

1. Closed Wallet Apps: These are mobile wallets provided by specific companies for their customers. The money in these wallets can only be used for transactions with the respective companies. For example, the Amazon Pay wallet can only be used for transactions on Amazon's platform.

2. Semi-Closed Wallet Apps: These mobile wallets can be used for transactions with multiple merchants, but they do not allow cash withdrawal or redemption. Examples of semi-closed wallet apps include Paytm and MobiKwik.

3. Open Wallet Apps: These are mobile wallets issued by banks. They can be used for all kinds of transactions, including cash withdrawals at ATMs. Examples of open wallet apps include Google Pay and Apple Pay, which are linked to users' bank accounts and can be used for a wide range of transactions.
